FAQs

What is the expected structure of CHEM 311 full lab reports?

Full lab reports must be formal, typed, and written in an impersonal voice. Reports should outline the chemistry and/or instrumentation principles, calibration techniques, data handling, experimental uncertainty, and the context/significance of results.

How should students schedule and submit technical and full lab reports?

Technical and full reports follow the completion of each lab, with full lab and technical reports due 11 calendar days after completion. Late penalties apply: 10% per week up to two weeks, after which reports are not accepted.

What should be included in the Principle of Method and Procedure sections?

The Principle of Method must explain how measured quantities relate to analyte concentration, including stoichiometry for wet chemical techniques or instrument operation for instrumental methods. The Procedure section should reference the lab manual and specify any modifications.
